50 will be in their outer or forwardly divergingpositions,
and these belts will be constantly running so that the
inner runs 76 thereof travel rearwardly as'indicated by ~
the arrows in FIG. 4. The constant drive to the belts is
established by a chain 120 between the baler shaft 34 and
the lower shaft 4% for the apparatus A. Since the belts
diverge as just described they are clear of the emerging '
bale 24, but as soon as the bale ‘24 emerges to a prede
termined extent, the bale moves the feeler 116 upwardly
so that the rockshaft 112 rocks in a counterclockwise
direction to move the valve piston 104 downwardly,
thereby establishing the transmission of ?uid under pres

- to move the belts to their parallel or operating positions.
The belts may be equipped with suitable lugs 122 to im
prove their traction on the bale so as to assure proper
travel of the bale rearwardly at an adequate speed to
cause it to be thrown directly to the trailing wagon W.
As the traveling ‘bale departs from the feeler 116, the
feeler returns to its normal position and the valve piston
104 is moved to its full-line position of FIG. 3. The
ners. ‘For example, on a corner the wagon will be mis
alined relative to the apparatus A and if the operator can
trip the mechanism prior to its normal time he can avoid
automatic tripping which might throw the bale during
that particular moment in which the wagon and baler are
out of alinement, in which case automatictripping might
result in missing the‘ wagon completely.

On the basis of the two control and operating means
illustrated, other designs will readily ‘suggest themselves‘.
Likewise, it should be recognized that many of the details
shown are only representative of how the invention may
I be exploited without departure from the spirit and scope
thereof.

What is claimed is:
v
I. For a baler having a bale case in which bales are
successively formed and discharged and including a dis
charge end through which bales successively emerge: bale
handling apparatus for causing successive emerging bales
to travel beyond said discharge end, comprising support
coordination between bale emergence, completion of a

end; a pair of conveyor belt means on the support means,

In a machine of this character, it is preferable that the
bales be made somewhat shorter than conventional bales.

when the bale following the emerging bale is completed,
so that the emerging bale is no longer needed as the

header, that function being now performed by the com
pleted succeeding bale. Likewise, as respects departure
of the traveling bale from the belts 50, it will be noted

driving engagement with the bale. As previously pointed
out, one signi?cant feature of the apparatus is that the
proximate ends of the belts may be located close to the
discharge end 22 of the bale case, and'this is possible be
cause of the bi-positionable proximate ends of the belts.
In other words, the belts are clear of the emerging bale
until the bale is freed from its function as part of the
baling operation. Consequently, the overall length of the
apparatus may be made relatively short.
In the modi?ed form of structure shown in FIG. 7, the
general characteristics as described above are the same,
with the exception that different means are provided for
causing the belts to move inwardly and outwardly. In‘this
case, instead of the feeler 116 and the power-operated
means, the operation depends upon a pair of levers 123,
pivoted at 125 respectively on the trough side ?anges 48, '
and projecting into the path of the emerging bale. The
belts may be biased to their outer positions as illustrated
in full lines. As the bale emerges onto the chute 42 and
between the forwardly diverging belts, the rear end there

so as to convey said bale beyond the bale case discharge
end.
